All others disregard and all replies offline, please... I get about 20-30 of these per day in my ldmd.log:May 11 13:24:37 noaaport dvbs_multicast[2238] ERROR: Gap in SBN last 16929982, this 16929984 May 11 13:24:37 noaaport dvbs_multicast[2238] ERROR: Gap in SBN last 16929986, this 16929988 May 11 13:24:37 noaaport dvbs_multicast[2238] ERROR: Gap in SBN last 16929996, this 16929999 May 11 13:24:37 noaaport dvbs_multicast[2238] ERROR: Gap in SBN last 16929999, this 16930002 May 11 13:24:37 noaaport dvbs_multicast[2238] ERROR: Gap in SBN last 16930004, this 16930007
And yet, my signal levels seem to be fine; variable bit error rate is mostly zero and never above 3 x 10(-7). I'm using a 3.6 m (12') dish, using a Norsat 3120 LNB, and a Novra box as a decoder. Signal strength is 78.
I compare my feed: http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_num_nc?NNEXRAD+noaaport.admin.niu.edu With LSU's: http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_num_nc?NNEXRAD+mistral.srcc.lsu.eduThey are very slightly different, flipping back and forth between the two using Internet Explorer 7, in the number of products received; I seem to miss a few here and there. Does anyone lose data...
1. When it rains? 2. When it is windy?Our rusty struts on our LNB will be replaced soon; it tends to vibrate slightly when the wind is over 40 MPH.
I don't notice any data loss, so it isn't very significant...but I want perfect reception, even in heavy rain.
